<p>A preferred embodiment of the present invention comprises a collapsible folding stand (100) for use with a horizontally oriented object such as a portable table saw that is attached to the stand wherein the stand has a front and a rear portion and is capable of being manipulated between open and closed positions. In the open position, the top frame (102) is horizontally oriented. In the closed position, the stand is generally vertically oriented as is the top frame. To move the rolling stand from its open position to its closed position, the user needs only to lift the handle (132) and the top frame (102) will then move to its generally vertical closed position where the latching mechanism (160) can then be engaged. Because of the mechanism advantage of the folding mechanism (112), moving between the open and closed positions in either direction requires very little effort by the user. The preferred embodiment has an integrated support leg (170) that can be selectively positioned and locked to provide increased stability and rigidity for the stand. The support leg has a locking mechanism (178), which when unlocked does not impede the easy movement between open and closed positions in either direction, and which when locked in the open position provides additional stability to the stand. The locking mechanism is operated by a single locking lever (214) and can be adjusted to compensate for wear or degree of force needed to lock the mechanism.</p> |
